Be it known that we, PAUL R. J 01mm, citizen of the United States, vand FRED W. F

Lonnme, a subject of the King of Norway,;

Worcester and State of Massachusetts, have invented; a ne'w'and useful Adjusting Mech- I anism for Cold-Rolling Mills, of which the following is a specification. 7

Our invention relates to the construction manipulatingthe housing screws of rolling construction and arrangement of the adjust.- ing mechanism used for adjusting the housing screws of'cold rolling mills. W One of the most important features in the operation of a cold rollin mill is in scour-j ing'and maintaining the fine adjustment .of the rolls'necessary to keep the top andbottom rolls in exact par-ullelismso' that the rolledproduct will boot exactly uniform thickness. In the operation ofcold rolling mills it is sometimes necessary to use one end more than the'oppositeyend of the roll bodies which causes the pressure on the roll necks on one end-0f therolls to be greater than that on the necks on the opposite end.

having the greatest pressure will wear muchmore rapidly than the others, which makes the-opposite roll housings of the mill indeso as to maintain the rolls in axialalinelnent. j o With .the adjusting gpurat-us heretofore e adjusting screws pinion which meshes with euehoftwo'gears on the adj usta-ble housing screws 15 urrnnged so as to be disconnected from the plmons' housing screw is then moved by means of .a' hand wrench in independentlyudjusting the screws. After the-necessary adjustment has tomesh with t e gears on the adjusting screws so that when the pinion is moved the screws will betm'ned or rotated in unison. Oneobject of our invention is-to provide a, screw adjusting mechanism hgvingnovel pear hereina'ter as I mills, and. more particularly relates to the sa'pl dies 10, of the usual on again caused tened to the top of'the-roll housing are connected end' di onn ted, and are ajd usted conj'oiiitly'i I and independently, as; found necessmrycordesirable.

' Another object of our invention is to pro- 1 vide a screw adjusting mcchalnisxn having novel .rneans whereby the housing screws are manipulated'in the successive adjustments of the rollsin' the roll. housings necessary 1n the operation of a rolling mill. 1 j
